IPCC SREX

IPCC Special Report

Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX)

From the report:

4.5.3.3. Attribution of Impacts to Climate Change: Observations and Limitations

There is high confidence, based on high agreement and medium evidence, that economic losses from weather- and climate-related disasters have increased. A key question concerns whether trends in such losses, or losses from specific events, can be attributed to climate change. In this context, changes in losses over time need to be controlled for exposure and vulnerability. Most studies of long-term disaster loss records attribute these increases in losses to increasing exposure of people and assets in at-risk areas, and to underlying societal trends – demographic economic, political, and social – that shape vulnerability to impacts.  Some authors suggest that a (natural or anthropogenic) climate change signal can be found in the records of disaster losses, but their work is in the nature of reviews and commentary rather than empirical research.

(Cites elided)

In plain language; there is no physical evidence that climate change has anything to do with losses from natural disasters; the so-called “extreme events”.

via Roger Peilke Jr who writes:

Kudos to the IPCC — they have gotten the issue just about right, where “right” means that the report accurately reflects the academic literature on this topic. Over time good science will win out over the rest — sometimes it just takes a little while.
